TECHNICAL FIELD

The present invention generally relates to the field of information processing technology, more particularly, to a method and system for searching for a web document.

BACKGROUND

With the rapid development and maturation of Web 2.0 technology, users are more active on the Internet than ever. Traditionally, Web contents are created by Web professionals. Nowadays, the majority of Web contents are contributed by a vast number of Web users, who can share useful information through various forms, e.g., tags, comments, questions, answers or votes. Meanwhile, more dynamic web technologies (e.g., JavaScript, Flash, JSP or ASP, HTML 5, etc.) have been or will be widely used during the development of Web 2.0 technology. Taking the Internet standard HTML 5 as an example, the predecessor of the HTML 5 draft is Web Application 1.0. It was proposed by WHATWG in 2004, and was accepted by W3C in 2007, and a new HTML task force was established. The first formal draft was published on Jan. 22, 2008. HTML 5 has two features: first, it enhances the representation performance of Web pages; besides being able to depict two-dimensional graphics, it has also prepared tags for playing videos and audios. Secondly, it is added with functions of Web applications such as local database. HTML 5 is not only for representing Web contents, rather, its mission is to bring the Web into a mature application platform on which videos, audios, images, animations and interactions with computers are all standardized (for more information, refer to www.w3.org/TR/html5//, www.html5.cn, etc.).

The development of dynamic web contents technologies presents great challenge to the search engine technology, since the current search engine technology is mainly directed to static web pages. In order to also search for dynamic web pages, the current search engine technology attempts to solve such a problem by recommending to web authors to use a standard platform. For example, the search engine corporation Baidu (Baidu is a trademark of the Baidu Corporation) has a program named Aladdin, which is an all-purpose open platform proposed by Baidu. It opens interfaces to owners of unique information data, so as to solve the problem that existing search engines are unable to capture and retrieve hidden web information. However, users may not want to use such a platform or similar technology to create web pages, and there will still be massive information that cannot be retrieved by the existing search engines.

BRIEF SUMMARY

In one aspect of the present invention, there is provided a system for searching for a web document. The system includes receiving means configured to receive a user's search request; searching engine configured to search for a web document related to the search request based on a web document index, and to determine a move path for accessing the web document based on a move path index of the web document; and sending means configured to send the move path for accessing the web document to the user.

Besides the traditional content index, the method of the present invention can first record and index the move path for obtaining dynamic contents. Then, during the search phase, the move path will be returned to the client together with the search result or according to the user's request. Finally, the client system may automatically locate the user's desired dynamic contents display status based on the move path. Therefore, it may help the search engine to retrieve contents that are difficult to be retrieved previously.

DETAILED DESCRIPTION

Now detailed description is presented by referring to exemplary embodiments of the present invention, and examples of the embodiments are illustrated pictorially in the accompanying drawing, wherein the same reference signs always denote the same elements. It should be appreciated that the present invention is not limited to the disclosed exemplary embodiments. It should be further appreciated that not every feature of the method and device is necessary for implementing the present invention as claimed by any one of the claims. In addition, in the entire disclosure, when a processing or method is illustrated or described, the steps of the method can be executed in any sequence or simultaneously, unless it can be clearly seen from the context that one step depends on another step executed previously. Further, the steps may have substantial time intervals there between.

FIG. 1 shows a first specific embodiment of a method for searching for a web document of the present invention. In the method, at step 101, a user's search request is received. At step 103, a web document related to the search request is searched for based on a web document index. Before receiving the user's search request, the search engine would create a move path index and a web document index of a corresponding web document. The move path refers to a detailed path record of the movement of a user interface element such as a cursor or the like on the web page caused by a user using a user interface input tool such as a mouse or by an automatic program, etc., and operations such as stopping or clicking of the user interface element performed on the web document when it moves to a specific position. Creating a web move path index comprises obtaining the move path of accessing a web document, and creating a move path index for the web document. There are various methods to obtain the move path of a web document, and here two methods are given as examples: the first method is to obtain the corresponding move path and the response position by simulating clicking on the web page. For example, the Web page is first loaded into a browser, and then a screenshot is made there from and potential clickable areas are analyzed, which may be realized automatically by using a program. The screenshot may be made by using the existing method of Java, java.swt.Robot.createScreenCapture. After making the screenshot, each pixel point in the screenshot is grouped. The grouping rule is that, if the color of a pixel is similar to that of an adjacent pixel (e.g., within two pixel points), then the two pixel points are placed in a same group. After this step, the size of each group is determined, which is calculated by the positions of the uppermost, lowermost, leftmost and rightmost pixel points. If the size of group is within a certain range, e.g., between 2×2 and 50×50, then it is considered that the group might represent a character on the web page. Then the groups of which the sizes meet requirements are merged by distance, and the method may be that those groups with a horizontal distance less than a certain value are merged into one group. After this step, the size of each group is determined once again. If the size is within a certain range, e.g., between 15×5 and 500×50, then the group might be a clickable area. Based on the analysis result, a real mouse is moved in the browser and a corresponding region is clicked on, which step can be realized by a software method, e.g., the existing method of Java, java.swt.Robt.mouseMove, mousePress and mouseRelease, and the like; meanwhile, the click path is recorded and the corresponding HTTP request and return result are tracked through a HTTP proxy. The above operations can be performed iteratively until there are no new clickable areas, The second method of obtaining the move path of a web document is to obtain a corresponding move path and response position by analyzing and executing specific code. For example, the method proposed in WO2010/114913A1 obtains the page contents in each different status by analyzing JavaScript functions. Specifically, it first obtains the source code the web page, then obtains the JavaScript information therein, and then analyzes the JavaScript to determine functions including Ajax invocation, and obtains the corresponding web contents by triggering the functions. The triggering positions on the web page to which these JavaScript functions correspond may also be obtained by analyzing the source code of the web page: since the links in a web page are generated by the source code in the web page, and if it is desired to obtain the links, the code in the web page must be executed or analyzed. There may be two possible outcomes if the code in a web page is executed: one is to generate clickable links (the A tags of HTML) on the web page, in which case it may not be possible to obtain the links by means of analysis; the other is to directly obtain the contents of the link by AJAX invocation after the code generated the link. Since the method of AJAX invocation is relatively fixed (through XMLHttpRequest or ActiveXObject object), the functions directly invoking AJAX can be found by analyzing the code. A web page link may be generated in multi-level function invocations and passed to an AJAX function. If the invocation levels are clear and do not depend on external variables and inputs, then the link may be calculated by means of analysis, so as to obtain the specific click positions of all the functions. In an aspect of the present invention, the web page may be a dynamic web page, which is at least one of dynamic web pages developed by using technologies such as JavaScript, Flash, JSP or ASP, HTML 5 or other future dynamic web page tools. In the following will be described how to create a move path index based on an obtained move path through specific examples.

Creating a web document index further comprises obtaining the move path for accessing the web document; obtaining the web document based on the move path; and creating a web document index for the web document. The web document can be accessed through the move path of the web document. After the contents of the web document are obtained, an index can be created for the web document according to existing document indexing technology. Those skilled in the art will know that creating an index for a known web document is a mature technology. For example, when there are documents T0=“it is what it is”, document T1=“what is it” and document T2=“it is a banana”, they may be indexed as “a”: {2}, “banana”: {2}, “is”: {0, 1, 2}, “it”{0, 1, 2}, “what”: {0, 1}, wherein “a”: {2} denotes that the word “a” appears in document T2. An Inverted index is “an index data structure storing a mapping from content, such as words or numbers, to its locations in a database file, or in a document or a set of documents.” Inverted index, wikipedia.org (23 Jun. 2011).

At step 105, the move path accessing the web document is determined based on the move path index of the web document. Since the move path of the web document that needs to be accessed has been indexed previously, according to the searched web document which the user desires to access, the move path corresponding to the web document can be determined by using the move path index. The user can access the web document by using the move path. At step 107, the move path for accessing the web document is sent to the user.

Generally, an existing search engine will return a search result with a summary of the web document (web page snapshot) to the user. Then as a second specific embodiment of a method of the present invention, the sending the move path for accessing the web document to the user may be to include the move path in the search result sent to the user, that is, to send to the user the search result together with the move path included in the search result; or it may be contemplated to send the move path separately when sending the search result, that is, to send the move path in response to sending the search result to the user. The move path may either be visible or invisible to the user; being visible means that the move path is included in the search result and displayed to the user. The web browser at the client may be added with a Robot/browser plugin, which can identify and parse the move path. Taking the solution in which the move path is invisible to the user as an example, the move path may be included in a HTML hidden tag (display=none in the style), which is not displayed on the web page, but the contents of which the plug-in can still detect. Of course, in the case of being visible, the browser plug-in can also identify the move path. When the user clicks in the search result, the browser will first jump to a page of the search engine to record the user's click, and then jumps to the actual search result page. If the user has installed the browser plug-in, when the browser plug-in detects that browser attempts to jump to the recording page of the search engine, the browser plug-in will scan the current page (i.e., the search result page); if the item clicked by the user in the search result includes the specific hidden tag, the plug-in will, after the search result page is opened, perform a series of clicks on the search result page according to the command specified by the tag to make it jump to the user's desired web document (web page status).

FIG. 2 shows a third specific embodiment of a method for searching for a web document of the present invention. In the method, at step 201, a user's search request is received; at step 203, a web document related to the search request is searched for based on a web document index. At step 205, a search result of the web document is sent to the user. At step 207, in response to receiving the user's request of browsing the web document, the move path for accessing the web document is determined based on the move path index of the web document, and the move path for accessing the web document is sent to the user. In this application scenario, the user's request to browser the document will first be sent by the web browser to the search engine sever, and the search engine server will search for the move path index to which the web document corresponds and determine the corresponding move path, and then the search engine server will send to the web browser the move path, based on which the web document can be accessed.

FIGS. 3 and 4 show an example of how to obtain the move path and create the dynamic web document index as well as the move path index. Suppose there is the following dynamic web page, http://abc.com/def, as shown in FIG. 3. Since the web document (contents) to which the tags such as Menu1 correspond can only be browsed by clicking, an existing search engine is unable to obtain the contents of the entire page, and typically can only capture the page contents as follows:

-   Document 1: Main Page Title Menu1 Menu 2 Menu 3 Menu4 Menu 5 Menu 6     Main Page Content Bla1 Bla2 Bla3.

Based on the traditional technology of document content indexing, the following reverse index can be obtained:

-   “main”: {Document 1} -   “page”: {Document 1} -   “title”: {Document 1} -   “menu 3”{Document 1} -   “bla3”{Document 1}

The new method proposed by the present invention lies in that:

-   by using at least one method of simulating clicking on the web     document and analyzing and executing specific code of the web     document, a page can be created for each web page status (web     document). In the following the page contents to which Menu3     corresponds will be taken as an example. Suppose the dynamic     contents of the page are displayed as follows: the document contents     to which the status corresponds are: -   MovePath (move path): M (400, 80): Click (M(400, 80)) denotes moving     to the web page position with a pixel coordinate of (400, 80), Click     denotes performing left key click of the mouse at the current     position.) -   Document1-DynmicStatus3: menu3 submenu3.1 submenu3.2 submenu3.3     submenu3.4

It may be supposed that the contents of submenu 3.2 being clicked are as follows (submenu3.1 is omitted from above, assuming it has no substantive document contents):

-   MovePath: M(400, 80): Click→M (400, 112): Click -   Document1-DynamicStatus3.2: item title, item description content, it     is a very good product.

Also, it may be supposed that the contents of submemu 3.3 being clicked are as follows:

-   MovePath: M(400,80):Click→sM(400, 122):Click -   Document1-DynamicStatus3.3 item title, item description content,     there are many gifts available.

It may be supposed that the contents of submenu 3.4 being clicked are as follows:

-   MovePath: M(400,80): Click→M(400, 132) Click -   Document1-DynamicStatus3.4 item title, item description content,     payment instructions -   wherein Document1-DynamicStatus 3.2 denotes the identification of     the page contents to which submenu 3.2 corresponds. Of course, those     skilled in the art may choose various identifications as appropriate     based on the present application, and here this is merely used as an     example. Here “item title” is a general designation. Based on the     above dynamic status contents, we can create indexes based on a     plurality of virtual documents for the dynamic web page,     http://abc.com/def, as follows:

web document index: “main”: {Document1} “page”: {Document1} “title”: {Document1, Document1-DynamicStatus3.2, Document1- DynamicStatus3.3, Document1-DynamicStatus3.4} ...... “menu3”: {Document1, Document1-DynamicStatus3} “bla3”: {Document1} ......

and create move path indexes according to the move paths corresponding to the web documents:

...... Document1-DynamicStatus3 : MovePath: M(400,80):Click Document1-DynamicStatus3.2: MovePath: M(400,80):Click Attorney Docket No. CN920110064US2 M(400, 112):Click Document1-DynamicStatus3.3: MovePath: M(400,80):Click M(400, 122):Click Document1-DynamicStatus3.4: MovePath: M(400,80):Click M(400, 132):Click ......

The association between the move path indexes and the web document indexes lies in web documents, e.g., “title” appears in the web document Document-DynamicStatus3.2, and the move path (index) to which the DynamicStatus3.2 corresponds is “Document1-DynamicStatus3.2: MovePath: M(400,80):Click M(400, 112):Click”.

Further, according to the layered structure of MovePath, the above indexes can be further optimized as (e.g., replacing some specific click path with a context document):

...... Document1-DynamicStatus3 : M(400,80):Click Document1-DynamicStatus3.2: Document1-DynamicStatus3 → M(400, 112):Click Document1-DynamicStatus3.3: Document1-DynamicStatus3 → M(400, 122):Click Document1-DynamicStatus3.4: Document1-DynamicStatus3 → M(400, 132):Click ......

The above structure can be used to quickly find the path result when the key word fall within two virtual documents respectively: for example, when the user inputs the key query words, submenu 3.2+item title, the corresponding virtual documents are: Document1-DynamicStatus3 and Document1-DynamicStatus3.2, respectively. However, since Document1-DynamicStatus3 already appears in the move path of Document1-DynamicStatus3.2, due to the association of the move paths, the document Document1-DynamicStatus 3.2 can be quickly returned from the above move path indexes to respond to the user's search requirement, without need to send the two move paths to the user. However, in searching of move paths, the association is mainly through web documents.

The web document indexes and the move path indexes are associated through web documents, and the web document indexes and the move path indexes may be stored separately. Of course, it may also be contemplated to merge the two index tables into one index table according to the identifications of web documents, such that the move path of a web document can be searched out together while the web document is searched for.

FIG. 5 shows a fourth specific embodiment of a method for searching for a web document of the present invention. In this specific embodiment, the interaction process between the search engine server and the user browser of the method of the present invention is described in detail. At step 500, the web document index and the move path index of the web document have been created according to the method described above. At step 501, the search engine server presents the search result to the user browser according to user's request and sends the move path to the user. At step 502, the user brows the search result and inputs a feedback into the user browser. At step 503, the user browser extracts the main web page from the content server according to the user feedback and the main web address provided by the search engine. At step 504, the user browser extracts the target page of the web page according to the move path provide by the search engine, and finally at step 505, presents the target page on the user browser. In addition, those skilled in the art will understand according to the present invention that it is also a feasible solution that the search engine sends the main page web address and the move path after obtaining the user's selection feedback.

FIG. 6 shows a fifth specific embodiment of a method for searching for a web document of the present invention. In this specific embodiment, the interaction process between the search engine server, the user browser and the web document server etc. of the method of the present invention is described in detail. At step 601, the user initiates a search request to the search engine server through the web browser, and the search engine server returns the search results (a catalog with abstracts) and move paths of web documents to the web browser in response to the search request (of course, the move path may also be retrieved and sent by the search engine server in response to the user's selection when the user really needs to browse a web document). At step 603, the user selects a search result and requests the web server to provide the corresponding contents. At step 604, the web server, in response to the request, returns the web page corresponding to the main address of the web document to the web browser. At step 605, the move path may be sent to the browser plug-in (Robot) by the browser, or the browser plug-in directly monitors the actions of the browser and obtains the move path as needed. Based on the move path, the browser plug-in can use the above-described simulating clicking technology to perform corresponding operations such as moving and clicking on the web page. At step 606, after finishing operations such as moving and clicking, the browser plug-in leaves the operation result to the web browser. At step 607, the web browser presents the target page.
